We live in Western WA. Mostly Rufous and Anas. Used to feed them, but had to stop as the battles over the feeder got very scary. Plus if the feeder was empty (it was located outside our kitchen window), they would hover outside the window staring at us. Lots of guilt when this happend. In the winter the Rufous somehow fly to Mexico. The Anas somehow make it thru the winter. Then the Rufous return, and the territorial battles start again. Here is a key for life, "Do not piss off a hummingbird."
